Argonauts of the Western Pacific

The coastal populations of the South Sea Islands, with very few exceptions, are, or were before their extinction, expert navigators and traders. Several of them had evolved excellent types of large sea-going canoes, and used to embark in them on distant trade expeditions or raids of war and conquest. The Papuo-Melanesians, who inhabit the coast and the out-lying islands of New Guinea, are no exception to this rule. In general they are daring sailors, industrious manufacturers, and keen traders. The manufacturing centres of important articles, such as pottery, stone implements, canoes, fine baskets, valued ornaments, are localised in several places, according to the skill of the inhabitants, their inherited tribal tradition, and special facilities offered by the district; thence they are traded over wide areas, sometimes travelling more than hundreds of miles.

Definite forms of exchange along definite trade routes are to be found established between the various tribes. A most remarkable form of intertribal trade is that obtaining between the Motu of Port Moresby and the tribes of the Papuan Gulf. The Motu sail for hundreds of miles in heavy, unwieldy canoes, called lakatoi, which are provided with the characteristic crab-claw sails. They bring pottery and shell ornaments, in olden days, stone blades, to Gulf Papuans, from whom they obtain in exchange sago and the heavy dug-outs, which are used afterwards by the Motu for the construction of their lakatoi canoes.
